Surely this isn’t news to you. If so, where you been?

Aside from all the great buzz being hyped about this movie, there’s been some great viral online marketing done. First, there was Why So Serious, then Commit Your Friend, and then live events covered by MTV interns (Hollywood and New York).

One thing caught my eye: a trailer recut into what it would look like if The Joker’s After-Effects-competent henchmen got a hold of it.

Ledger aside, it’s a chilling effect on the dark nature of the character and the movie. And to think, someone might say, “Hey, they’re ruining the scenes! They’re literally drawing on what WB spent millions of dollars to shoot and create!”

Let’s learn a lesson from the biggest blockbuster hit of 2008 (yes, bigger than Iron Man): no footage (and no brand) is too precious to not take a chance at telling a compelling story.

If you have trustworthy people with video-editing skills, let them mash up some footage. Let them experiment with your brand in their eyes. After all, they’re already brand ambassadors to their circle. Why not give them some slack on the leash. You might find viral gold.
